1. Maximum operating reliability

Steel bearings with reinforced PTFE lining.
Stem in anti-blow out design.

2. Long service life, zero maintenance

The unique AMRING® sealing system allows fluid contact with disc and liner only. No risk of corrosion, straightforward dismantling.
The keyed or splined positive connection between shaft and disc ensures optimum power transmission.

3. Direct mounting of pneumatic, electric and hydraulic actuators possible
4. Absolutely reliable shut-off and sealing
The unique AMRING ® sealing system makes for tight valve closure and reliable sealing to atmosphere.

The spherically machined valve disc and the matching spherically moulded liner ensure perfectly tight shutoff, even if the valve is actuated frequently.
The specially designed liner also provides a tight seal at the flange connections, eliminating the need for an extra gasket.
